1 Claim. (Cl. 215-63) This invention relates to containers and moreparticularly to an easily operated lid therefor.

It is an object of the present invention to provide a convenient lid forshallow jars, such as cosmetic jars, which will enable such jars to beeasily opened and closed during use with wet or slippery hands.

Another object of the present invention is to provide a closure lid forshallow cosmetic jars which will enable such jars to betightly sealedwhen in a closed position and which will prevent unnecessary waste orloss of the contents of such jar.

Other objects of the invention are to provide a jar lid bearing theabove objects in mind which is of simple construction, has a minimumnumber of parts, is inexpensive to manufacture and efficient inoperation.

For other objects and for a better understanding of the invention,reference may be had to the following detailed description taken inconjunction with the accompanying drawing, in which:

Figure 1 is a side elevational view, with parts broken away, of a jarlid assembly made in accordance with the present invention in operativeuse;

Figure 2 is a top plan view of the assembly shown in Figure 1 in acompletely closed position;

Figure 3 is a transverse cross sectional view of the assembly shown inFigure 2, taken along line 3--3 of Figure 2; and

Figure 4 is a'bottom plan view of the assembly shown in Figure 2.

Referring now more in detail to the drawing, a jar lid assembly made inaccordance with the present invention is shown to include a main wall'18 having a central circular opening extending therethrou-gh which isdefined by a substantially inverted truncated conical surface 20 whichextends through and communicates with the upper and lower sides thereof.An annular collar 12 integral with and depending from the lower side ofthe main wall 18 is provided with internal threads 14 that threadedlyengage with a correspondingly threaded neck 16 of any shallow type jar.A hinge pin 26 eX- tending through hinge portions 24 of a pair of lidsections 22 pivotally supports such lid sections 22 upon the oppositeupper side of the main wall 18 for selective movement relative theretobetween a normally closed and open position.

As is more clearly shown in Figure 3 of the drawing, each lid section 22is provided With a segmental circular peripheral surface 23 thatcorresponds in inclination to the surface 20 of the opening through themain wall 18, thus providing a tight sealing fit in the closed position.

Patented Aug. 30, 1960 2 A radially outwardly extending marginalportion, including hand holds 28, limits the downward movement of thelid sections 22 toward the closed position and also provides convenientmeans for raising and lowering the lid sections during use.

It will now be recognized that this device, which can be preferablyconstructed of molded plastic material, may be readily attached to alltypes of shallow cosmetic jars. In the normally closed position, thecontents of the jar are conveniently sealed against evaporation andwaste, while it only requires a flick of the finger to open such jarsfor use by exerting an upward movement against the finger grips 28, inthe manner shown in Figure 1. If desired, this lid assembly may beconveniently used to replace conventional types of lids, and may beeconomically reused with similar jars so as to prolong the normal usefullife thereof.

While various changes may be made in the detail construction, it shallbe understood that such changes shall be within the spirit and scope ofthe present invention as defined by the appended claim.

What I claim as new and desire to protect by Letters Patent of theUnited States is:

A jar lid comprising, in combination, a main substantially fiat wall ofannular shape, said main wall including a substantially invertedtruncated inwardly and downwardly converging continuous conical edgesurface defining a central substantially circular opening in said mainwall providing access therethrough from an upper outer side thereof to alower inner side thereof, substantially circular coupling means carriedby the lower inner side of said main wall radially outwardly of saidcentral opening in downwardly directed relation to said main wall andcomprising an internally threaded collar integral with said main wallfor threaded attachment to an exteriorly threaded neck of a jar, andclosure means carried by the upper outer side of said main wall forcontrolling communication through said opening and comprising a pair ofsubstantially similar send-circular lid sections and a hinge pinpivotally centrally connecting said lid sections together for individualpivotal movement between open and closed positions relative to said mainwall opening, marginal portions of each of said semicircular lidsections defining substantially inverted truncated inwardly downwardlyconverging conical surfaces corresponding to the similar conicalsurfaces defining said opening and adapted for sealing engagementtherewith when said lid sections are in closed relationship with saidopening in said main wall, each of said lid sections including radiallyoutwardly extending tabs overlying said main wall and extending beyondthe downwardly directed threaded collar for digital engagement forcontrolling pivotal movement of said lid sections between normallyclosed and open positions.
